Description
The PAM8004 is a 3Wm Class-D audio amplifier. It offers low THD+N, allowing it to achieve high quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters, in order to save system cost and PCB area. With the same numbers of external components, the efficiency of the PAM8004 is much better than that of Class-AB cousins. It can extend the battery life, ideal for portable applications The PAM8004 is available in SOP-16L package.
